Callidiopis

Small to medium-sized dark brown beetles with filiform antennae reaching almost to apices of elytra. Frontoclypeus transverse. Gland opening at base of mandibles absent. Eyes moderately coarsely facetted, deeply emarginate. Antennal tubercles broadly separated, distant from mandibular articulation. Antennal foramen depressed. Antennal scape distinctly shorter than pronotum; pedicel as long as wide; antennomere 3 longer than scape; antennomeres 3–7 with short apical spines or prominent angles. Pronotum subquadrate with dorsal nodules, lateral margins rounded. Prosternal process moderately broad, weakly expanded apically. Procoxal cavities rounded without lateral extensions; open externally. Procoxae weakly projecting below prosternal process. Mesoventrite flat in front of mesocoxae; mesoventral intercoxal process broad, without secondary articulation, notched apically. Mesocoxal cavities closed to mesepimeron; mesotrochantin hidden. Elytra without costae or ivory-coloured markings; punctures clearly visible not in regular rows, apices rounded. Femora strongly clavate; tibiae not flattened.

Callidiopis is an endemic Australian genus known from south-eastern Australia, where it ranges from the New England Tablelands in New South Wales, via the Australian Capital Territory to Tasmania and to the Flinders Ranges of South Australia. Callidiopis scutellaris was introduced to New Zealand at the beginning of the 20th Century and is currently the most common cerambycid associated with dead Eucalyptus material in New Zealand.
